A 33-year-old Sour Lake man was arrested Friday for "super" aggravated sexual assault of a 7-year-old girl, according to Sour Lake police reports.

A 28-year-old woman also was arrested Friday for failing to report the assaults, which is a Class A misdemeanor, Sour Lake Police Chief Mike Holzapfel said.

Holzapfel said he believes that this is the first "super" aggravated sexual assault of a child case in Hardin County.

On May 28, Sour Lake officers began an investigation into an incident that occurred in Sour Lake, according to a probable cause affidavit.

"The defendant restrained her by tying her up with rope and duct tape before sexually assaulting her," according to the probable cause affidavit.

The child had spoken of four separate assault incidents in past months, according to the probable cause affidavit.

"Due to the additional aggravated factor of being restrained with rope and duct tape, the defendant is being charged with 'super' aggravated sexual assault of a child," according to the probable cause affidavit.

Child protective services took custody of the child and two other young children in her family, Holzapfel said.

Police continue to investigate, and further arrests are possible, Holzapfel said.

"Super" aggravated sexual assault of a child is a first-degree felony with a minimum punishment of 25 years without parole, Holzapfel said.

Bond set on Donald Wayne Ener Jr. was $20,000. No bond had been set on the woman, and both remained in the Hardin County jail.
